Bussmann BG3011SQ Fuse Block for Circuit Protection Assemblies

The Bussmann BG3011SQ Fuse Block is engineered to securely hold and mount one or more fuses within an electrical circuit assembly. This fuse block family is available in amperage/voltage configurations ranging from 0.18-15A at 600V up to 25-30A at 480V, allowing electricians and panel builders to select the rating that matches the specific circuit protection requirement. As a component of the broader Bussmann line of circuit protection products, the BG3011SQ fuse block provides a dependable mounting and connection point for fuse holders used in panels, control systems, machinery, and other electrical enclosures. Fuse blocks like this are commonly used to organize and protect wiring by allowing fuses to be inserted, removed, and replaced without disturbing the surrounding circuit connections, which supports straightforward maintenance since individual fuses can be serviced without rewiring the entire circuit. This Bussmann fuse block is intended for use as an original equipment or replacement component in professional electrical installations where dependable fuse mounting is required across a range of amperage and voltage ratings.

Bussmann BG3031S – Frequently Asked Questions

1) What amperage and voltage ratings does the Bussmann BG3011SQ fuse block come in?
Two ratings are offered under the BG3011SQ family. The BG3011SQ itself covers 0.18-15A at 600V, and the BG3031S covers 25-30A at 480V. Pick the one that brackets the fuse amperage your circuit calls for, and note the voltage drops to 480V on the higher-amperage version, so a 600V circuit needs the BG3011SQ.
2) Can I replace an existing Bussmann fuse block in a control panel with the BG3011SQ?
Yes, within its rating range. The BG3011SQ is intended as an original equipment or replacement component for Bussmann fuse-based circuit protection assemblies in panels, control enclosures, machinery and power distribution gear. Match the replacement to the amperage and voltage of the block coming out: 0.18-15A at 600V for the BG3011SQ, 25-30A at 480V for the BG3031S.
3) What should I use instead of the Bussmann fuse block if I need 30A three-pole protection at 600V?
The Bussmann BG3031S configuration covers 25-30A at 480V, so a 600V 30A opening is outside it. The Littelfuse LFR60030-3CID is a Class R fuse block rated 600V 30A, which matches that requirement. Class R blocks are rejection-style, so the fuses specified must be Class R to seat.
4) What is the closest alternative to the Bussmann BG3011SQ fuse block for a 600V 15A circuit?
For a 600V 15A circuit, the Littelfuse LFG60015-1SQDINR Class G fuse block is rated 600V 15A and mounts on DIN rail. The Bussmann BG3011SQ covers 0.18-15A at 600V in its base configuration. The difference to confirm before ordering is mounting method and fuse class: the Littelfuse unit is a Class G block on DIN rail, so the enclosure needs a rail and the fuses must be Class G.
5) Should I use a panel-mount fuse block like the Bussmann BG3011SQ or a DIN rail mount block?
The BG3011SQ is built for mounting inside electrical panels, control enclosures and equipment wiring as a fixed fuse mounting point. If your enclosure is laid out around DIN rail and you want the block to clip onto existing rail instead, a DIN rail unit such as the Littelfuse LFG60015-1SQDINR Class G block (600V 15A) is the format to look at. Littelfuse also offers the LD Series POWR-BLOKS in a bolt-in mounting style if you are landing the block directly to a panel subplate.
6) Is the Bussmann BG3011SQ a fuse, a fuse holder, or the base they mount to?
It is the block, not the fuse. The BG3011SQ securely holds and mounts one or more fuses within a circuit assembly and gives the fuse holder a stable connection point. Fuses are ordered separately to the amperage you need, inside the block's range of 0.18-15A at 600V or 25-30A at 480V on the BG3031S.
7) What is the exact part number to order for the 25-30A Bussmann fuse block?
The 25-30A at 480V version carries manufacturer part number BG3031S. The 0.18-15A at 600V version is BG3011SQ, which is also the series designation for the family.
8) Is a Littelfuse POWR-BLOK a direct substitute for a Bussmann BG3011SQ fuse block?
Not directly. The Littelfuse LD Series POWR-BLOKS is a bolt-in mounting fuse block, meaning it fastens to a panel subplate through bolt holes. The Bussmann BG3011SQ family is specified by amperage and voltage range, from 0.18-15A at 600V up to 25-30A at 480V. Treat the POWR-BLOK as an alternative only where the bolt-in footprint and the fuse class match what the assembly is built around.
9) I want a DIN rail mounted fuse block rather than the Bussmann BG3011SQ - what are my options?
The Littelfuse LFG60015-1SQDINR is a DIN rail mount Class G fuse block rated 600V 15A, which suits control panels already built on rail. The Bussmann BG3011SQ is intended for mounting within panels, control enclosures, and equipment where a dedicated fuse block is required, so confirm your enclosure's mounting provision before switching between the two.
10) Does a fuse block let me change a fuse without rewiring the circuit?
That is the point of it. The BG3011SQ holds the fuse in a fixed mounting and connection point so the fuse can be pulled and replaced without disturbing the surrounding wiring connections. For maintenance teams it means an individual fuse gets serviced without taking the circuit apart.
